Round duration - 90 minutes
Round difficulty - Medium
This round had 3 coding questions of Medium to Hard level of difficulty.
Given an integer N
representing the number of pairs of parentheses, find all the possible combinations of balanced parentheses using the given number of pairs.
Generate all possible combinations of balanced parentheses for a given number of pairs.
Use recursion to generate all possible combinations of balanced parentheses.
Keep track of the number of open and close parentheses used in each combination.
Return the valid combinations as an array of strings.
You are given a long type array/list ARR
of size N
, representing an elevation map. The value ARR[i]
denotes the elevation of the ith
bar. Your task is to determine th...
Calculate the total amount of rainwater that can be trapped between given elevations in an array.
Iterate through the array and calculate the maximum height on the left and right of each bar.
Calculate the amount of water that can be trapped at each bar by taking the minimum of the maximum heights on the left and right.
Sum up the trapped water at each bar to get the total trapped water for the entire array.
You are given a grid containing oranges where each cell of the grid can contain one of the three integer values:
Find the minimum time required to rot all fresh oranges adjacent to rotten oranges.
Create a queue to store the coordinates of rotten oranges and perform BFS to rot adjacent fresh oranges.
Track the time taken to rot all fresh oranges and return -1 if not all fresh oranges can be rotten.
Update the grid with the new state of oranges after each second.
Handle edge cases such as empty grid or no fresh oranges present.

Implement a queue using stacks following FIFO principle.
Use two stacks to simulate a queue.
For enQueue operation, push elements onto stack1.
For deQueue operation, if stack2 is empty, pop all elements from stack1 and push onto stack2, then pop from stack2.
For peek operation, if stack2 is empty, pop all elements from stack1 and push onto stack2, then return top of stack2.
For isEmpty operation, check if both stack1 and st...

Merge overlapping intervals and return sorted list of merged intervals by start time.
Sort the intervals based on start time.
Iterate through intervals and merge overlapping ones.
Return the merged intervals in sorted order.

Round difficulty - Medium
This round had 2 coding questions - first one related to Binary Tree and the second one was a simple question from Bit Manipulation. This was followed by some questions from OOPS.
You are given a Binary Tree, and you need to determine the length of the diameter of the tree.
The diameter of a binary tree is the length of the longest path betwe...
The task is to find the diameter of a binary tree, which is the length of the longest path between any two end nodes in the tree.
Traverse the tree to find the longest path between two nodes.
Keep track of the maximum diameter found during traversal.
The diameter may not necessarily pass through the root node.
Consider both left and right subtrees while calculating the diameter.
Example: For input 1 2 3 4 -1 5 6 -1 7 -1 -1

The fir...
The problem involves determining if it is possible to reorder the digits of a given integer to form a power of 2.
Iterate through all possible permutations of the digits of the given integer.
Check if any of the permutations form a power of 2.
Return 1 if a valid permutation is found, else return 0.
Advantages of OOP include code reusability, modularity, and easier maintenance.
Code reusability: Objects can be reused in different parts of the program, reducing redundancy.
Modularity: OOP allows for breaking down complex problems into smaller, more manageable parts.
Easier maintenance: Changes to one part of the codebase do not necessarily affect other parts, making maintenance easier.
Encapsulation: Data hiding and ab...
Access specifiers define the level of access to class members in Object-Oriented Programming.
Access specifiers include public, private, protected, and default
Public members are accessible from outside the class
Private members are only accessible within the class
Protected members are accessible within the class and its subclasses
Default access is when no access specifier is specified
Round duration - 30 Minutes
Round difficulty - Easy
This was my last round and I hoped it to go good just like the other rounds. The interviewer was very straight to point
and professional. The interview lasted for 30 minutes.
